FIELD OF THE INVENTION

This invention relates to novel lactams having drug and bio-affecting properties, their pharmaceutical compositions and methods of use. These novel compounds inhibit the processing of amyloid precursor protein and, more specifically, inhibit the production of Aβ-peptide, thereby acting to prevent the formation of neurological deposits of amyloid protein. More particularly, the present invention relates to the treatment of neurological disorders related to β-amyloid production such as Alzheimer's disease and Down's Syndrome.

BACKGROUND OF THE INVENTION

Alzheimer's disease (AD) is a degenerative brain disorder characterized clinically by progressive loss of memory, temporal and local orientation, cognition, reasoning, judgment and emotional stability. AD is a common cause of progressive dementia in humans and is one of the major causes of death in the United States. AD has been observed in all races and ethnic groups worldwide, and is a major present and future health problem. No treatment that effectively prevents AD or reverses the clinical symptoms and underlying pathophysiology is currently available (for review, Dennis J. Selkoe; Cell Biology of the amyloid (beta)-protein precursor and the mechanism of Alzheimer's disease, Annu Rev Cell Biol, 1994, 10: 373-403).

Histopathological examination of brain tissue derived upon autopsy or from neurosurgical specimens in effected individuals revealed the occurrence of amyloid plaques and neurofibrillar tangles in the cerebral cortex of such patients. Similar alterations were observed in patients with Trisomy 21 (Down's syndrome), and hereditary cerebral hemorrhage with amyloidosis of the Dutch-type. Neurofibrillar tangles are nonmembrane-bound bundles of abnormal proteinaceous filaments and biochemical and immunochemical studies led to the conclusion that their principle protein subunit is an altered phosphorylated form of the tau protein (reviewed in Selkoe, 1994).

Biochemical and immunological studies revealed that the dominant proteinaceous component of the amyloid plaque is an approximately 4.2 kilodalton (kD) protein of about 39 to 43 amino acids. This protein was designated Aβ, β-amyloid peptide, and sometimes β/A4; referred to herein as Aβ. In addition to deposition of Aβ in amyloid plaques, Aβ is also found in the walls of meningeal and parenchymal arterioles, small arteries, capillaries, and sometimes, venules. Aβ was first purified, and a partial amino acid reported, in 1984 (Glenner and Wong, Biochem. Biophys. Res. Commun. 120: 885-890). The isolation and sequence data for the first 28 amino acids are described in U.S. Pat. No 4,666,829.

Compelling evidence accumulated during the last decade revealed that Aβ is an internal polypeptide derived from a type 1 integral membrane protein, termed b amyloid precursor protein (APP). β APP is normally produced by many cells both in vivo and in cultured cells, derived from various animals and humans. AP is derived from cleavage of β APP by as yet unknown enzyme (protease) system(s), collectively termed secretases.

The existence of at least four proteolytic activities has been postulated. They include β secretase(s), generating the N-terminus of Aβ, a secretase(s) cleaving around the 16/17 peptide bond in Aβ, and y secretases, generating C-terminal Aβ fragments ending at position 38, 39, 40, 42, and 43 or generating C-terminal extended precursors which are subsequently truncated to the above polypeptides.

Several lines of evidence suggest that abnormal accumulation of Aβ plays a key role in the pathogenesis of AD. Firstly, Aβ is the major protein found in amyloid plaques. Secondly, Aβ is neurotoxic and may be causally related to neuronal death observed in AD patients. Thirdly, missense DNA mutations at position 717 in the 770 isoform of β APP can be found in effected members but not unaffected members of several families with a genetically determined (familiar) form of AD. In addition, several other b APP mutations have been described in familiar forms of AD. Fourthly, similar neuropathological changes have been observed in transgenic animals overexpressing mutant forms of human β APP. Fifthly, individuals with Down's syndrome have an increased gene dosage of b APP and develop early-onset AD. Taken together, these observations strongly suggest that Aβ depositions may be causally related to the AD.

It is hypothesized that inhibiting the production of Aβ will prevent and reduce neurological degeneration, by controlling the formation of amyloid plaques, reducing neurotoxicity and, generally, mediating the pathology associated with Aβ production. One method of treatment methods would therefore be based on drugs that inhibit the formation of Aβ in vivo.

Methods of treatment could target the formation of Aβ through the enzymes involved in the proteolytic processing of β amyloid precursor protein. Compounds that inhibit β or γ secretase activity, either directly or indirectly, could control the production of Aβ. Advantageously, compounds that specifically target γ secretases, could control the production of Aβ. Such inhibition of β or γ secretases could thereby reduce production of Aβ, which, thereby, could reduce or prevent the neurological disorders associated with Aβ protein.

Aβ is an approximately 4.2 kilodalton (kD) protein of about 39 to 43 amino acids found in amyloid plaques, the walls of meningeal and parenchymal arterioles, small arteries, capillaries, and sometimes, venules. The isolation and sequence data for the first 28 amino acids are described in U.S. Pat. No 4,666,829. The 43 amino acid sequence is:

1 Asp Ala Glu Phe Arg His Asp Ser Gly Tyr 11 Glu Val His His Gln Lys Leu Val Phe Phe 21 Ala Glu Asp Val Gly Ser Asn Lys Gly Ala 31 Ile Ile Gly Leu Met Val Gly Gly Val Val 41 Ile Ala Thr.

However, a skilled artisan knows that fragments generated by enzymatic degradation can result in loss of amino acids 1-10 and/or amino acids 39-43. Thus, an amino acid sequence 1-43 represents the maximum sequence of amino acids for Aβ peptide.

The term “APP”, as used herein, refers to the protein known in the art as β∇amyloid precursor protein. This protein is the precursor for Aβ and through the activity of “secretase” enzymes, as used herein, it is processed into Aβ. Differing secretase enzymes, known in the art, have been designated β secretase, generating the N-terminus of Aβ, a secretase cleaving around the 16/17 peptide bond in Aβ, and “γ secretases”, as used herein, generating C-terminal Aβ fragments ending at position 38, 39, 40, 41, 42, and 43 or generating C-terminal extended precursors which are subsequently truncated to the above polypeptides.

The compounds herein described may have asymmetric centers. Compounds of the present invention containing an asymmetrically substituted atom may be isolated in optically active or racemic forms. It is well known in the art how to prepare optically active forms, such as by resolution of racemic forms or by synthesis from optically active starting materials. Many geometric isomers of olefins, C═N double bonds, and the like can also be present in the compounds described herein, and all such stable isomers are contemplated in the present invention. Cis and trans geometric isomers of the compounds of the present invention are described and may be isolated as a mixture of isomers or as separated isomeric forms. All chiral, diastereomeric, racemic forms and all geometric isomeric forms of a structure are intended, unless the specific stereochemistry or isomeric form is specifically indicated.

The term “substituted,” as used herein, means that any one or more hydrogens on the designated atom is replaced with a selection from the indicated group, provided that the designated atom's normal valency is not exceeded, and that the substitution results in a stable compound. When a substituent is keto (i.e., ═O), then 2 hydrogens on the atom are replaced.

When any variable (e.g., R^(5b)) occurs more than one time in any constituent or formula for a compound, its definition at each occurrence is independent of its definition at every other occurrence. Thus, for example, if a group is shown to be substituted with 0-2 R^(5b), then said group may optionally be substituted with up to two R^(5b) groups and R^(5b) at each occurrence is selected independently from the definition of R^(5b). Also, combinations of substituents and/or variables are permissible only if such combinations result in stable compounds.

When a bond to a substituent is shown to cross a bond connecting two atoms in a ring, then such substituent may be bonded to any atom on the ring. When a substituent is listed without indicating the atom via which such substituent is bonded to the rest of the compound of a given formula, then such substituent may be bonded via any atom in such substituent. Combinations of substituents and/or variables are permissible only if such combinations result in stable compounds.

Methods for the synthesis of succinylamino lactams are known in the art and are disclosed in a number of references including PCT publication number WO 96/29313, which is hereby incorporated by reference.

Disubstituted succinate derivatives can be prepared by a number of known procedures. The procedure of Evans (D. A. Evans et al, Org. Synth. 86, p83 (1990)) is outlined in Scheme 1 where acylation of an oxazolidinone with an acylating agent such as an acid chloride provides structures 1. Alkylation to form 2 followed by cleavage of the chiral auxiliary and subsequent alkylation of the dianion of the carboxylic acid 3 provides a variety of disubstituted succinates which can be separated and incorporated into structures of Formula (I) by those skilled in the art. Additional examples are found in P. Becket, M. J. Crimmin, M. H. Davis, Z. Spavold, Synlett, (1993), 137-138, incorporated herein by reference.

Deprotection of the tert-butyl ester is accomplished by treatment with 50% trifluoroacetic acid.

Additional methods useful for the preparation of succinate derivatives are known by those skilled in the art. Such references include, McClure and Axt, Bioorganic & Medicinal Chemistry Letters, 8 (1998) 143-146; Jacobson and Reddy, Tetrahedron Letters, Vol 37, No. 46, 8263-8266 (1996); Pratt et al., SYNLETT, May 1998, p. 531; WO 97/18207; and WO 98/51665.

Additional methods useful for the preparation of succinate derivatives are disclosed in WO00/07995 and WO 00/38618, which are hereby incorporated in their entirety by reference.

A variety of compounds of Formula (I) can be prepared by methods described in Scheme 4. The protected α amine 3 of the a amino-e caprolactam can be prepared by methods well known in the literature for amino protecting groups as discussed in Theodora W. Greene's book “Protective Groups in Organic Synthesis”, like N-Boc using di-t-butyldicarbonate in an appropriate solvent like DMSO. A sulfur atom can be introduced into the ring providing L-α amino-β thio-ε caprolactam according to the procedure in S. A. Ahmed et al, FEBS Letters, (1984), vol. 174, pages 76-9 (Scheme 3).

One skilled in the art can extend this methodology to the synthesis of β amino and oxygen containing rings by analogy. The sulfur-containing molecules can also be oxidized to the sulfoxide and sulfone by methods known to one skilled in the art.

The lactam nitrogen of compound 13 can be alkylated by generating the anion with bases such as LDA, lithium bis(trimethylsilyl)amide or sodium hydride in solvents like THF, with or without cosolvents such as DMPU or HMPA and reacting this with a variety of groups containing leaving groups (X″) like bromide, iodide, mesylate or tosylate. Alkylating agents such as a bromo amides, ketones and acids can be prepared by a number of literature methods including halogenation of amino acids by diazotization or are commercially available. Other suitable alkylating agents such as alkyl, allylic and benzylic halides can be formed form a variety of precursors such as free-radical addition of halides or activation of alcohols, and other chemistries known to those skilled in the art. For discussion of these types of reactions, see Carey, F. A. and Sundberg, R. J., Advanced Organic Chemistry, Part A, New York: Plenum Press, 1990, pages 304-305, 342-347, 695-698.

The N-Boc protecting group can be removed by any number of methods well known in the literature like TFA in methylene chloride to give the compound 15. The amine 15 can be coupled to an appropriately substituted carboxylic acid or acid chloride by methods well described in the literature for making amide bonds, like TBTU in DMF with a base like NMM to give the elaborated compound 16. Compounds 16 can be alkylated using standard bases like LDA, NaH, or NaHMDS to deprotonate the amide followed by addition of an alkylating agent with an appropriate leaving group like halide, mesylate, or triflate in an appropriate solvent to provide compounds 17 with an R⁶ substituent. The t-butyl ester is then removed by treatment with TFA in methylene chloride to give the carboxylic acid 17.

It is understood that methods useful for the preparation of W—X—Y—Z derivatives, on a non-commercial scale, are known by those skilled in the art or readily ascertainable from the literature. Such methods useful for the preparation of W—X—Y—Z derivatives are disclosed in WO00/07995 and WO 00/38618, which are hereby incorporated in their entirety by reference.

The final compounds 18 were prepared by treating the activated carboxylic acid of 17 with an appropriately substituted amine. For instance, activation of the carboxylic acid with HATU (O—(7-azabenzotriazol-1-yl)-1,1,3,3,-tetramethyluronium hexafluorophosphate) or PyBOP (benzotriazole-1-yl-oxy-tris-pyrrolidino-phosphonium hexafluorophosphate) or other coupling agents known to those skilled in the art allows condensation with ammonia to form primary amides. Similarly, condensation of the activated acid with hydroxylamine hydrochloride provides the hydroxamic acid, or reaction with a primary or secondary amine provides the substituted amine derivative. Activation of the acid with PyBrOP (bromo-tris-pyrrolidino-phosphonium hexafluorophosphate) followed by addition of an alcohol and 4-dimethylaminopyridine allows formation of the ester directly. For additional acylation reactions see for example Carey, F. A. and Sundberg, R. J., Advanced Organic Chemistry, Part A, New York: Plenum Press, 1990, pages 475-479.

Additional Examples of compounds of Formula (I) can be prepared as shown in Scheme 5. A suitable resin for solid phase synthesis such as Fmoc (Fluorenylmethylcarbonyl)-protected hydroxylamine bound to polystyrene beads can be purchased from Novabiochem, Inc. Deprotection of the Fmoc group under standard conditions using 20% piperidine in DMF provides trityl-linked hydroxylamine resin. Coupling of a fluorenylmethyl-protected succinic acid derivative such as 20 with a coupling agent such as HATU in a suitable solvent like DMF or N-methylpyrrolidinone provides the support-bound hydroxamate 21. The Fluorenylmethyl ester can be removed using 20% piperidine in DMF to provide the free carboxylic acid which can be coupled to amines like the caprolactam 22 (which is available using chemistry outlined in Scheme 4) using PyBOP (benzotriazole-1-yl-oxy-tris-pyrrolidino-phosphonium hexafluorophosphate) and a suitable base like DIEA in DMF or NMP. The support-bound intermediate 23 can then be elaborated to biaryl structures of the type 24 using typical Suzuki coupling conditions employing a catalyst such as Palladium complexes like tetrakis(triphenylphosphine)-palladium with 2M aqueous sodium carbonate as a base in a suitable solvent like THF or DME and an excess of a boronic acid. The final compounds are liberated from the support employing dilute (5%) trifluoroacetic acid in CH₂Cl₂ and purified by conventional chromatography.

General Procedure for Solid-phase Synthesis According to Scheme 5.

Resin 20 of Scheme 5:

Fmoc-protected resin 19 (2.0 g, 0.78 mmol/g, 1.56 mmol) is purchased from Novabiochem and swelled in 20 ml of CH₂Cl₂ for 1 hour. The CH₂Cl₂ is removed and the resin is then treated with 25% v/v piperidine in DMF (8 mL) and allowed to shake slowly for 16 h. The solvent was removed by filtration and the resin was shaken with an additional 8 mL of 25% v/v piperidine in DMF for 2 h at room temperature. The solvents were removed by filtration, and the resin 20 was rinsed 3× with 20 mL of DMF, 3× with 20 mL of methanol, and 3× with 20 mL of CH₂Cl₂ and dried in vacuo.

Succinate 10 of Scheme 2:

Succinate 9 is prepared according to the literature procedure (P. Becket, M. J. Crimmin, M. H. Davis, Z. Spavold, Synlett, (1993), 137-138; WO 97/18207; WO 98/51665). Succinate 9 (17.8 g, 66 mmol) is dissolved in 250 mL of ethyl acetate and placed in a Parr shaker bottle. To the solution is added 890 mg of 5% palladium on carbon, and the bottle is pressurized to 40 psi with hydrogen gas and shaken for 2.5 h at room temperature. The hydrogen is removed and the palladium catalyst is removed by filtration through a pad of celite. Concentration of the ethyl acetate solution provides 17.5 g (98%) of succinate 10. No further purification is necessary. MS (M−H)⁺=271.

Succinate 21 of Scheme 5:

Succinate 10 (6.3 g, 23.1 mmol) is dissolved in 125 mL of CH₂Cl₂ and 4.8 g (23.3 mmol) of dicyclohexylcarbodiimide is added. The solution is stirred at room temperature for 30 min and then 4.6 g (23.4 mmol) of 9-fluorenemethanol is added followed by 122 mg (1 mmol) of 4-dimethylaminopyridine. After 5 h of stirring at room temperature, the reaction solution was diluted with an additional 100 mL of CH₂Cl₂ and filtered through a pad of celite to remove precipitated dicyclohexylurea. The solution was then washed 3× with 50 mL of a 1N HCl solution, 3 × with 50 mL of a saturated sodium bicarbonate solution, and 2× with 50 mL of brine. The crude product was dried over MgSO₄ and soncentrated onto 15 g of silica gel. Chromatography eluting with a gradient of 2.5% to 5% ethyl acetate/hexanes provided 6.4 g (61%) of the diester as an oil. The purified diester (6.4 g 14.2 mmol) is then dissolved in 25 mL of CH₂Cl₂, 25 mL of trifluoroacetic acid is added, and the reaction solution is stirred at room temperature for 2 h. The reaction solution is directly concentrated in vacuo to an oil which is then redissolved in 25 mL of toluene and reconcentrated, followed by drying in vacuo to provide 6.3 g (98%) of the desired succinate 9 as an oil which solidifies on standing. MS (M+Na)⁺=471, (M+2Na)⁺=439.

Caprolactam 23 of Scheme 5:

Boc-caprolactam 14 (5.0 g, 21.9 mmol) is dissolved in 60 mL of THF and chilled to -78° C. To the chilled solution is added 24 mL of a 1.0 M solution of lithium bis(trimethylsilyl)amide in THF, and the solution was brounght to 0° C. and stirred for 15 min. To the anion solution was added 6.5 g (22 mmol) of 3-iodobenzyl bromide (Aldrich) and the the solution was allowed to warm to room temperature and stirred for 18 h. The reaction solution was diluted with 50 mL of water and extracted 3× with ethyl acetate. The combined organic layers were dried over MgSO₄ and concentrated in vacuo. The crude product was purified by chromatography eluting with a gradient of 5-20% ethyl acetate/hexanes to afford 7.0 g (72%) of the title compound as a white solid. MS (M+Na)⁺=467.

Resin 22 of Scheme 5:

Resin 22 (2.0 g, 0.78 mmol/g, 1.56 mmol) was swollen in 3 mL of DMF. In a separate flask, 1.85 g (4.68 mmol) of succinate 21 was dissolved in 3 mL of DMF and 2.5 mL of N,N-diisopropylethylamine (14 mmol) wsa added, followed by 1.81 g (4.68 mmol) of HATU. The solution containing the active ester was added to the slurried resin and the reaction suspension was slowly shaken for 18 h. The resin was then washed 3× with 20 mL of DMF, 3× with 20 mL of methanol, and 3× with 20 mL of CH₂Cl₂. Loading of the resin was determined by Fmoc quantitation to be 0.25 mmol/g, see Reddy, M.

Resin 22 (2.0 g, 0.25 mmol/g, 0.5 mmol) was suspended in 10 mL of 25% piperidine in DMF. The suspended resin was shaken for 30 min at room temperature, and then the resin was washed 3× with 20 mL of DMF, 3× with 20 mL of methanol, and 3× with 20 mL of CH₂Cl₂. Deprotected resin (1.0 g, 0.25 mmol) was swollen in 2 mL of DMF. To the slurry was added 650 mg (1.25 mmol) of PyBOP and 217 mL (1.25 mmol) of DIEA. Separately, 443 mg (0.97 mmol) of caprolactam 23 was dissolved in 2 mL of DMF and 436 mL (2.5 mmol) of DIEA was added. The caprolactam solution was added to the resin slurry and the resin was mixed for 18 h at room temperature. The solvents were then removed and the coupling was repeated, with shaking at room temperature for 6 h. The resin was then washed 3× with 10 mL of DMF, 3× with 10 mL of methanol, and 3× with 10 mL of CH₂Cl₂.

Products 25 of Scheme 5:

A 70 mg (17.5 mmol) portion of resin 24 was suspended in 1 mL of THF in a screw-cap vial. To the slurry was added a boronic acid (0.15 mmol), 150 mL of a 2 M solution of sodium carbonate, and 15 mg (13 mmol) of tetrakis(triphenylphosphine)palladium. The vial was tightly closed and heated to 60° C. for 16 h using a dry heater on a shaker table. The solvents were then removed by filtration and the resin was washed 3× with THF (2 mL), 3× with methanol (2 mL), 3× with water, and 3× with CH₂Cl₂. The resins were then placed in a glass vial and cleaved with 1 mL of 5% trifluoroacetic acid in CH₂Cl₂ for 30 min. The solution ws filtered off and the resin was washed with an additional 2 mL of CH₂Cl₂ and the combined filtrates were evaporated to dryness to yield the crude products 25. The products were purified by chromatography eluting with 10-100% ethyl acetate in hexanes to yield 13.0 to 6.0 mg (14-60%) of the final products.

Additional Examples of compounds of Formula (I) can be prepared as shown in Scheme 6. A suitable resin for solid phase synthesis such as Fmoc (Fluorenylmethylcarbonyl)-protected peptide amide linker (PAL)-derivatized polystyrene beads can be purchased from Perkin Elmer Biosystems, Inc. Deprotection of the Fmoc group under standard conditions using 20% piperidine in DMF provides the free benzylamine. Coupling of a succinic acid derivative such as 28 (which is available using chemistry outlined in Scheme 4) with a coupling agent such as HATU in a suitable solvent like DMF or N-methylpyrrolidinone provides the support-bound amide 29. The support-bound intermediate 29 can then be elaborated to biaryl structures of the type 24 using typical Suzuki coupling conditions employing a catalyst such as Palladium complexes like tetrakis(triphenylphosphine)-palladium with 2M aqueous sodium carbonate as a base in a suitable solvent like THF or DME and an excess of a boronic acid. The final compounds are liberated from the support employing 50% trifluoroacetic acid in CH₂Cl₂ and can be purified by conventional chromatography or preparative HPLC.

The internal phenyl ring can be exchanged for a pyridine ring using chemistry outlined in Scheme 7. The chloromethyl pyidine 33 is prepared using a known procedure reported in Nutaitis, Charles F.; Ledeboer, Mark W. Org. Prep. Proced. Int. (1992), 24(2), 143-6 Incorporated herein by reference. After freebasing the pyridine, alkylation with the Boc-caprolactam provides pyridine intermediate 34, which can be elaborated to the protected amide 35 with succinate 10. Substitution can then be introduced using Suzuki methodology employing a palladium source such as tetrakis(triphenylphosphine) palladium(0) or bis(diphenylphosphinoferrocene) palladium(II) dichloride and a suitable base such as sodium carbonate or triethylamine in a solvent such as THF or toluene containing 10% methanol. Stille chemistry is also possible using a suitable palladium source such as tetrakis(triphenylphosphine)palladium(0) and an aryl or vinyl tin derivative in a solvent such as benzene, toluene, or xylenes. The tert-butyl ester is then deprotected under standard acidic conditions using trifluoroacetic acid and the amide is formed under standard conditions to provide products 36.

Separately, 1.8 g (7.8 mmol) of caprolactam 13 is dissolved in 40 mL of dry THF and chilled to −78° C. To the solution was added 8.7 mL of a 1M solution of sodium bis(trimethylsilyl) amide. The solution was brought to 0° C. and stirred for 30 min. To the resultant anion was added a solution of 1.7 g (8.3 mmol) of pyridine 33 free base dissolved in 40 mL of THF. The resulting reaction solution was stirred at room temperature for 18 h and then heated to 50° C. and stirred an additional 3 h. The reaction solution was allowed to cool and then 50 mL of water was added and the aqueous layer was extracted 2× with 100 mL of ethyl acteate. The combined organic layers were dried and concentrated under reduced pressure to provide the crude product which was purified by chromatography eluting with 20 to 100% ethyl acetate in hexanes to provide 1.5 g (51%) of caprolactam 34 as an oil.

Amide 35:

Caprolactam 34 (0.40 g, 1.0 mmol) is dissolved in 20 mL of 50% trifluoroacetic acid in CH₂Cl₂ and stirred at room temperature for 30 min. The solvents were then removed under reduced pressure and the resulting oil was redissolved in 5 mL of toluene and reconcentrated to remove residual TFA. Separately, 0.270 g (1.0 mmol) of succinate 10 was dissolved in 5.0 mL of dry DMF and 0.44 mL (4 mmol) of N-methylmorpholine was added followed by 0.50 g (1.3 mmol) of HATU and the resulting solution was stirred at room temperature for 30 min. The crude deprotected caprolactam from above was dissolved in 5.0 mL of dry DMF and added to the succinate solution and the resulting solution was heated to 50° C. and stirred for 2 days. The solution was then diluted with 20 mL of water and extracted with 3 50 mL portions of ethyl acetate.

The compounds of Formula (I) of the present invention can also be prepared from aminolactam 42 and succinic acid derivatives 41 using amide bond syntheses known in the art, including methods commonly used in peptide syntheses, such as HATU, TBTU, BOP, pyBOP, EDC, CDI, DCC, hydroxysuccinimide, mixed carboxylic anhydride, and phenyl ester mediated couplings, as illustrated in Scheme 9 for the synthesis of aminolactam 43, an embodiment of the present invention.

Depending on the structure of the final product, it is appreciated by those skilled in the art that protecting groups or precursor functionality convertable to the desired groups may be desireable. Protecting groups and their use in synthesis are described in Green and Wuts, Protective Groups in Organic Synthesis, (Wiley 1991). The use of protecting groups is further illustrated in Scheme 10, in which the succinate half-ester 44 (Becket et al., Synlett 1993, 137-138) is coupled to the aminobenzodiazepine 45 (Sherrill and Sugg, J. Org. Chem. 1995, 60, 730-734; Bock et al., J. Med. Chem., 1993, 36, 4276-4292) to give ester 46, followed by conversion of the ester group to the primary amide 47.

UTILITY

Aβ production has been implicated in the pathology of Alzheimer's Disease (AD). The compounds of the present invention have utility for the prevention and treatment of AD by inhibiting Aβ production. Methods of treatment target formation of Aβ production through the enzymes involved in the proteolytic processing of 3 amyloid precursor protein.

β Amyloid Precursor Protein Accumulation Assay (β APPA assay)

An assay to evaluate the accumulation of AP protein was developed to detect potential inhibitors of secretases. The assay uses the N 9 cell line, characterized for expression of exogenous APP by immunoblotting and immunoprecipitation.

The effect of test compounds on the accumulation of AP in the conditioned medium is tested by immunoprecipitation. N 9 cells are grown to confluency in 6-well plates and washed twice with 1× Hank's buffered salt solution. The cells are starved in methionine/cysteine deficient media for 30 min., followed by replacement with fresh deficient media containing 150 uCi Tran35S-LABEL™ (ICN). Test compounds dissolved in DMSO (final concentration 1%) are added, over a range of 1 picomolar to 100 micromolar, together with the addition of the fresh media containing Tran35S-LABEL™. The cells are incubated for 4 h at 37° C. in a tissue culture incubator.

At the end of the incubation period, the conditioned medium is harvested and pre-cleared by the addition of 5 μl normal mouse serum and 50 ul of protein A Sepharose (Pharmacia), mixed by end-over-end rotation for 30 minutes at 4° C., followed by a brief centrifugation in a microfuge. The supernatant is then harvested and transferred to fresh tubes containing Sug of a monoclonal antibody (examples of antibodies include but are not limited by, clone 1101.1, directed against an internal peptide sequence in Aβ; or 6E10 from Senetek; or 4G8 from Senetek; additionally polyclonals from rabbit antihuman Aβ from Boehringer Mannheim) and 50 μl protein A Sepharose. After incubation overnight at 4° C., the samples are washed three times with high salt washing buffer (50 mM Tris, pH 7.5, 500 mM NaCl, 5 mM EDTA, 0.5% Nonidet P-40), three times with low salt wash buffer (50 mM Tris, pH 7.5, 50 mM NaCl, 5 mM EDTA, 0.5% Nonidet P-40), and three times with 10 mM Tris, pH 7.5. The pellet after the last wash is resuspended in SDS sample buffer (Laemmli U.K. Cleavage of structural proteins during the assembly of the head of bacteriphage T4. Nature 227, 680-5, 1970.) and boiled for 3 minutes. The supernatant is then fractionated on either 10-20% Tris/Tricine SDS gels or on 16.5% Tris/Tricine SDS gels. The gels are dried and exposed to X-ray film or analyzed by phosphorimaging. The resulting image is analyzed for the presence of Aβpolypeptides. The steady-state level of Aβ in the presence of a test compound is compared to wells treated with DMSO (1%) alone. A typical test compound in this assay blocks AP accumulation in the conditioned medium, and is considered active with an IC₅₀ less than 100 μM.

C-Terminus b Amyloid Precursor Protein Accumulation Assay (CTF assav)

The effect of test compounds on the accumulation of C-terminal fragments is determined by immunoprecipitation of APP and fragments thereof from cell lysates. N 9 cells are metabolically labeled, as above, with media containing Tran35S-LABEL™, in the presence or absence of test compounds. At the end of the incubation period, the conditioned medium are harvested and cells lysed in RIPA buffer (10 mM Tris, pH 8.0 containing 1% Triton X-100, 1% deoxycholate, 0.1% SDS, 150 mM NaCl, 0.125% NaN₃). Again, lysates are precleared with 5 ul normal rabbit serum/50 ul protein A Sepharose, followed by the addition of BC-1 antiserum (15μl;) and 50μl protein A Sepharose for 16 hours at 4° C. The immunoprecipitates are washed as above, bound proteins eluted by boiling in SDS sample buffer and fractionated by Tris/Tricine SDS-PAGE. After exposure to X-ray film or phosphorimager, the resulting images are analyzed for the presence of C-terminal APP fragments. The steady-state level of C-terminal APP fragments is compared to wells treated with DMSO (1%) alone. A typical test compound in this assay stimulates C-terminal fragment accumulation in the cell lysates, and is considered active with an IC₅₀ less than 100 μM. Accumulation-Release Assay This immunoprecipitation assay is specific for g secretase activity (i.e., proteolytic activity required to generate the C-terminal end of Aβ either by direct cleavage or generating a C-terminal extended species which is subsequently further proteolyzed). N 9 cells are pulse labeled with media containing Tran35S-LABELTM in the presence of a reported g secretase inhibitor (MDL 28170; Higaki J, Quon D, Zhong Z, Cordell B. Inhibition of beta-amyloid formation identifies proteolytic precursors and subcellular site of catabolism. Neuron 14, 651-659, 1995) for 1 h, followed by washing to remove 35S radiolabel and MDL 28170. The media is replaced and test compounds are added over a dose range (for example 0.1 nM to 100 uM). The cells are chased for increasing periods of times and Aβ is isolated from the conditioned medium and C-terminal fragments from cell lysates (see accumulation assay above). The activity of test compounds are characterized by whether a stabilization of C-terminal fragments is observed and whether Aβ is generated from these accumulated precursor. A typical test compound in this assay prevents the generation of Aβ out of accumulated C-terminal fragments and is considered active with an IC₅₀ less than 100 μM.

The dosage regimen for the compounds determined from the present invention will, of course, vary depending upon known factors, such as the pharmacodynamic characteristics of the particular agent and its mode and route of administration; the species, age, sex, health, medical condition, and weight of the recipient; the nature and extent of the symptoms; the kind of concurrent treatment; the frequency of treatment; the route of administration, the renal and hepatic function of the patient,and the effect desired. An ordinarily skilled physician or veterinarian can readily determine and prescribe the effective amount of the drug required to prevent, counter, or arrest the progress of the condition.

Advantageously, compounds determined from the present invention may be administered in a single daily dose, or the total daily dosage may be administered in divided doses of two, three, or four times daily.

The compounds identified using the present invention can be administered in intranasal form via topical use of suitable intranasal vehicles, or via transdermal routes, using those forms of transdermal skin patches wall known to those of ordinary skill in that art. To be administered in the form of a transdermal delivery system, the dosage administration will, of course, be continuous rather than intermittant throughout the dosage regimen.

In the methods of the present invention, the compounds herein described in detail can form the active ingredient, and are typically administered in admixture with suitable pharmaceutical diluents, excipients, or carriers (collectively referred to herein as carrier materials) suitably selected with respect to the intended form of administration, that is, oral tablets, capsules, elixirs, syrups and the like, and consistent with conventional pharmaceutical practices.

For instance, for oral administration in the form of a tablet or capsule, the active drug component can be combined with an oral, non-toxic, pharmaceutically acceptable, inert carrier such as lactose, starch, sucrose, glucose, methyl callulose, magnesium stearate, dicalcium phosphate, calcium sulfate, mannitol, sorbitol and the like; for oral administration in liquid form, the oral drug components can be combined with any oral, non-toxic, pharmaceutically acceptable inert carrier such as ethanol, glycerol, water, and the like. Moreover, when desired or necessary, suitable binders, lubricants, disintegrating agents, and coloring agents can also be incorporated into the mixture. Suitable binders include starch, gelatin, natural sugars such as glucose or β∇ lactose, corn sweeteners, natural and synthetic gums such as acacia, tragacanth, or sodium alginate, carboxymethylcellulose, polyethylene glycol, waxes, and the like. Lubricants used in these dosage forms include sodium oleate, sodium stearate, magnesium stearate, sodium benzoate, sodium acetate, sodium chloride, and the like. Disintegrators include, without limitation, starch, methyl cellulose, agar, bentonite, xanthan gum, and the like.

The compounds determined from the present invention can also be administered in the form of liposome delivery systems, such as small unilamellar vesicles, large unilamallar vesicles, and multilamellar vesicles. Liposomes can be formed from a variety of phospholipids, such as cholesterol, stearylamine, or phosphatidylcholines.

Compounds of the present invention may also be coupled with soluble polymers as targetable drug carriers. Such polymers can include polyvinylpyrrolidone, pyran copolymer, polyhydroxypropylmethacrylamide-phenol, polyhydroxyethylaspartamidephenol, or polyethyleneoxide-polylysine substituted with palmitoyl residues. Furthermore, the compounds determined from the present invention may be coupled to a class of biodegradable polymers useful in achieving controlled release of a drug, for example, polylactic acid, polyglycolic acid, copolymers of polylactic and polyglycolic acid, polyepsilon caprolactone, polyhydroxy butyric acid, polyorthoesters, polyacetals, polydihydropyrans, polycyanoacylates, and crosslinked or amphipathic block copolymers of hydrogels.

Gelatin capsules may contain the active ingredient and powdered carriers, such as lactose, starch, cellulose derivatives, magnesium stearate, stearic acid, and the like. Similar diluents can be used to make compressed tablets. Both tablets and capsules can be manufactured as sustained release products to provide for continuous release of medication over a period of hours. Compressed tablets can be sugar coated or film coated to mask any unpleasant taste and protect the tablet from the atmosphere, or enteric coated for selective disintegration in the gastrointestinal tract. Liquid dosage forms for oral administration can contain coloring and flavoring to increase patient acceptance.

In general, water, a suitable oil, saline, aqueous dextrose (glucose), and related sugar solutions and glycols such as propylene glycol or polyethylene glycols are suitable carriers for parenteral solutions. Solutions for parenteral administration preferably contain a water soluble salt of the active ingredient, suitable stabilizing agents, and if necessary, buffer substances. Antioxidizing agents such as sodium bisulfite, sodium sulfite, or ascorbic acid, either alone or combined, are suitable stabilizing agents. Also used are citric acid and its salts and sodium EDTA. In addition, parenteral solutions can contain preservatives, such as benzalkonium chloride, methyl- or propyl-paraben, and chlorobutanol.

Suitable pharmaceutical carriers are described in Remington's Pharmaceutical Sciences, Mack Publishing Company, a standard reference text in this field.
